LOS ANGELES — A 13-year-old California boy plans to try to climb Mount Everest in a quest to reach the summits of the highest peaks on all seven continents.

If Jordan Romero succeeds, he’ll become the youngest person to conquer the world’s highest mountain.

Jordan will attempt the ascent to 29,035 feet with his father and his father’s girlfriend, both experienced outdoors people who have helped train the teenager for top-level mountaineering.

When Jordan was only 9, a school mural of the seven summits inspired his ambitious goal.

“I told my dad about it and he didn’t say no. He just explained the difficulties and what I’d have to do. We started training right away,” said Jordan, who’s set to depart for Nepal Monday night.

At age 10, he became the youngest American to summit Mount Kilimanjaro, Africa’s highest peak. He’s steadily checked off four of the tallest peaks since then, including Alaska’s Mount McKinley, which many consider to be a technically harder climb than Everest.

The teenager’s planned Everest ascent is making the mountaineering community think hard about how young is too young to climb such a dangerous mountain.

Gordon Janow, a guide with Alpine Ascents International in Seattle, said there’s not a lot of research on the short- and long-term effects of high altitude on children, whose brains and bodies are still developing.

“These days, it’s moving so fast. It’s a 10-year-old sailing around the world this year and an 8-year-old the next,” Janow said. “What’s reasonable anymore?”

Jordan’s mother, Leigh Anne Drake, said she is bracing herself for two long months when the only news of her son will come from a blinking dot that represents his GPS device on a topographical map of Everest.

“From the second he leaves my arms until he’s back, it’s like I can’t breathe and I can’t cry,” Drake said, her voice cracking. “But at the same time, I’m so overjoyed that’s he’s getting the chance to do and see all of these amazing things.”
